Workflow-Based Image Processing Grid Platform and Remote Sensing Application

To facilitate the requirements of remotely sensing applications,a workflow-based image processing grid platform is built to support resource sharing and cooperation.It is a flexible and dynamic image processing problem-solving environment.Grid workflow technology can facilitate agile requirements of various applications,general service broker can invoke heterogeneous grid services simply,and workflow models are defined by the more operable extended directed acyclic graph language.Remote sensing applications have been applied on the platform successfully.
